Have you ever noticed that people aren't really perfectly symmetrical? Well, I thought I might see what would happen if I made a few friends faces perfectly symmetrical. They came out looking quite frightening. So, I had to include just a little bit of asymmetry in order to make them look normal. Below are the original pictures and the (almost) symmetrized pictures.

This is a picture of Suzan and Arwen at GHP.

This is the same photo after I symmetrized Suzan's face. I also removed the glare from the flash and any unsightly blemishes. It's not perfectly symmetrical though. I purposely desymmetrized her mouth to make her look more natural, and recolored her hair and face on the right side to make the border with Arwen's face look right.

And this is Arwen's makeover. Most of her face has been symmetrized. Her braces have been removed (to my best guess) and the glare and blemishes have been removed as well.

Conclusion: No matter what you look like in a particular picture, the real you is hiding just under the surface.

As evidence that you must be beautiful to begin with for this treatment to be effective, I submit this rendition of my own self-portrait:

And here's a note from the Illustrious Suzan herself:

venusvirtuosa: i, Suzan the Illustrious, am not in any way offended by quintopia's alteration of my semblance. in fact, i am grateful and flattered that he should even take the time to do so for one so inferior as myself. so leave him alone.
